Characteristics of the double-torsion test to determine the R-curve of ceramic materials
(2006-10-01)
Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance ...

Alternative dynamic torsion test to evaluate the elastic modulus of polymers
(Iop Publishing Ltd, 2020-09-01)
This work presents an alternative for the determination of the torsion modulus, G, of polymers. These materials may be subjected to shear stresses in some structural applications; thereby, the knowledge of G is of great ...
Torsion modulus using the technique of mechanical spectroscopy in biomaterials
(2017-05-01)
This work presents a new alternative to studying and determining the shear or torsion modulus, G. For this purpose, a measuring system was constructed with a rotational motion sensor coupled to a torsion pendulum that ...
Influence of nonlinear stiffness on the dynamics of a slender elastic beam under torsional oscillations
(2014)
This study focuses on analysing the effects of nonlinear torsional stiffness on the dynam-ics of a slender elastic beam under torsional oscillations, which can be subject to helical buckling.The helical buckling of an ...
Torsion modulus with CaCO3 fillers in unsaturated polyester resin - mechanical spectroscopy
(Assoc Brasil Polimeros, 2022-01-01)
This work presents an alternative to studying and determining the torsion modulus, G, in composites. For this purpose, we use a measuring system with a rotation motion sensor coupled with a torsion pendulum that allows for ...
Study of the dimensions of double-torsion test specimens
(ABM, ABC, ABPol, 2008-09-01)
Double-torsion tests were carried out to ascertain whether a thin test specimen would affect the results of this test. The tests involved two test specimen sizes, one with a thickness five-fold greater than the particle ...
